The rectangle below has an area of 4(x+3) [4 is width, x+3 is length] square units. when the dimensions of the rectangle are doubled, the area of the new rectangle in terms of x is 8(2x+6). [ 8 being the width and 2x+6 being the length.] will the ratio of the area of the original rectangle to the larger rectangle be the same for any positive value of x?

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
